Planting time and planting depth

It is important to plant flower bulbs at the right time. Flower bulbs that
bloom early (from January to March) should be planted in September/October. The
best time to plant the ones that bloom later (March-May) is October/November.

A general rule for the planting depth is to plant the bulbs at a depth at
least twice the height of the bulb (a minimum of 5 cm / 2 inches). Not planting
bulbs deep enough results in poor rooting that leads, in turn, to an uneven
emergence of short spindly plants. Planting too deep can result in rotting as
well as late emergence.
